Working Theory

A popular alteration amongst vehicle owners is to decat the exhaust system or install an aftermarket header, to unlock the horsepower of the vehicle. Nowadays, exhaust gas is controlled through two to up to four exhaust oxygen sensors, at least one upstream sensor that controls the fuel management system, and at least one post that monitors catalyst function. When the aftermarket headers are installed or catalytic converters are removed on your Mitsubishi Space Gear, the result is a catalyst efficiency ECM code alerting the Electronic Control Module that the catalyst is missing or not working properly. The modified engine now produces a larger amount of exhaust gases than allowed. Obviously you do not want to drive your car with a constant SES light, in addition your Mitsubishi Space Gear will not pass emission test in many US states or countries with an illuminated CEL. The ultimate solution is to install an O2 sensor simulator wired up to the downstream exhaust air fuel sensor’s harness in order to emulate a properly functioning oxygen sensor. EZ CEL Fix oxygen sensor eliminator sends the Power Control Module with mimicked, fluctuating voltage signal and tricks the Electronic Control Module into thinking the emissions are within permitted range. Your Mitsubishi Space Gear oxygen sensor simulator will allow you to drive your vehicle without catalyst and still keep the warning light off.

Notes

In case of a single oxygen sensor or dual pipe exhaust system fitted with two exhaust air fuel sensors only, the oxygen sensor simulator wires to these ports.

Headers require both up- and downstream Oxygen sensor emulation.

upstreamo2 sensor has to work flawlessly. Slow signal of precat oxygen sensor may prevent the aftercat oxygen sensor emulator from working.

Oxygen sensor simulator is a racing part. It is not CARB approved. Please be aware of the bylaws and regulations, O2 sensor eliminator is not street legal in several US states and countries.

Mitsubishi Space Gear EZ CEL Fix Oxygen Sensor Simulator is a must-have device if you are about remove the catalytic converter or even if you installed aftermarket header, a performance catback system or free flow converter. Are you chasing after the ultimate solution for MIL light issue? Then you’ve come to the right place.

Are you concerned with remedying the ECM safe / limp mode was tripped by your exhaust alteration? Are you sick and tired of resetting the Engine management over and over again? Get rush and install our oxygen sensor emulator on your Mitsubishi Space Gear. With minimum efforts you can rectify the ECU safe / limp mode all on your own, as long as you are mechanical and electrical minded. Conduct the setup and enjoy the warning light-free driving.

How can I figure out my sensor is a zirconia type?

Zirconia type oxygen sensors have 1 to 4 wires. 1 to 3 wires indicate a zirconia narrowband O2 sensor definitely. In the case of 4 wires, two of the wires have to be identical for heater, whilst the rest two wires have to be different for signal sender and signal ground. Always reference the sensor-side colors of the wires coming out off of sensor head. ECU-side colors may convert through the plugs.

How to find out if it's a narrowband or wideband?

Typically 1 to 4-wire sensors are narrowband. There are exceptions though. A narrowband oxygen sensor's signal is constantly fluctuating in a range of 0 to 1.0 Volts depending on oxygen content in the exhaust gas. Any oxygen sensor that produces higher voltages, is determined to be a wideband oxygen sensor. Keep in mind, although a 4-wire O2 sensor can be wideband too, in common sense only 5 or 6-wire sensors are called wideband. If your sensor has more than 4-wires, oxygen sensor is not applicable.

Which sensor has to be tricked?

In general: the downstream but upstream has to work flawless in full range. If you intend to buy a simulator hence decatting, header or modified exhaust, the downstream sensor has to be fooled by all means. See position diagram .

Headers or precat gutting requires upstream simulator as well.

Questions and answers

- Can I be positive this chip fixes my CEL issue for good and all? - Yes, Magnum oxygen sensor simulator produces a random fluctuation having assigned with suitable cycle and wave accepted by the ECU. Rest assured, all oxygen sensor signal related codes will be gone. Upstream sensor if any has to be in good condition though. Please see prerequisites pertaining to sensor type and quantity of simulators. - What if I simply eliminate factory oxygen sensor? - Oxygen sensor removal will not remedy CEL issue. Suitable fluctuating signal is fundamental to be delivered by the ECU. Zero volt signal triggers another trouble code. - Why is it so important to cancel the trouble code? - While check engine light is on, ECU restricts the engine performance and vehicle is running in safe / limp mode. MPG is also affected negatively. - Do I need to buy a heated simulator or I can stick with this cheaper EZ CEL Fix? - If you can use the heater of the factory oxygen sensor(s), you may wire up this #795 EZ CEL Fix. Heated simulator #661 allows you to remove or eliminate the stock oxygen sensor completely. - What about 'oxygen sensor bungs' 'mini cats' or any other piggybacks are also supposed to sort our FI problems? - The market is teeming with physical gadgets aiming to fix CEL issues. Vast majority of them doesn't take effect on OBDII vehicles made after 1996. They often don't work even on early fuel injected cars. If your vehicle had been manufactured after 1996 or you drive an early model controlled by a sensitive ECU, these gadgets won't help. The definite solution is a circuit conditions realistic signal, as if a working oxygen sensor would be screwed in the factory exhaust. - Can I rally my two harnesses into one simulator? - No, simulators can't be spliced. Get rid of oxygen sensor related CEL issue yet today. Flat catalytic converter gutting or plain-tube decats will spoil low- and mid-end torque hence ruined engine flush due to inadequate exhaust back pressure and higher block temperature thus valves, cylinder head and other engine parts are constantly being exposed to undesired extra heat. True enough, maximum horsepower increases it still pertains to a higher RPM which perishes dynamic kick out acceleration throughout the RPM range, mostly on automatic vehicles, therefore to save money on fuel and enhance low and mid-end torque, highly recommended to install a reliable Decat . Plain decatting is judged unprofessional among serious tuners and enthusiasts. Injected gasoline engines controlled by Electronic Control Unit (ECU) or alias Electronic Control Management (ECM) have oxygen sensor or O2 sensors to measure the amount of oxygen contained in the exhaust gas. These sensors deliver the ECU fluctuating voltage according to the actual oxygen consistence of air fuel mixture. When exhaust system is decatted or heavily modified, ECU is reading an oxygen sensor signal being inconsistent with other engine sensor's signal, or signal is out of the range yet accepted, an O2 sensor-related trouble code will be triggered ending up in check engine light issue. CEL or MIL or FI errors abbreviate these failures. While check engine light is on, ECU runs in so called lean limp mode. Safe mode restricts both the fuel trim and the ignition timing and develops an overall limitation on performance, until problem diagnosed and resolved definitely. Therefore if you modified your engine with any upgrade causes the oxygen sensor deliver lower signal than normally, you need to wire up an Oxygen Sensor Simulator. Although your ECU will be tweaked, mixture's air fuel ratio still will remain incorrect hence decatting or any other exhaust modification. Simulators help you remedy CEL problems but will not achieve that basic remapping is crucial when decatting or modifying an exhaust.

de-catted truck is craving for o2 bypass

When i spotted on eZ CELL to my R 3500 and consulted part info, I got the grasp of what I needed to purchase. No qualms when your de-catted truck is craving for o2 bypass these are must. The only minus they don 't make dual sims.

will walk you through everything

I stumbled across this web site after searching high and low for a piggyback for my CEL to be cured. I am a broke amateur I still coped with the set up by myself. Tech support was a wealth of help. I recommend this o2 bypass to people who are having similar screwy sensor codes issues even after replacing all the stinking sensors! Easy to install the simulator will walk you through everything, codes are tripped no more and trust me I felt the firmer shifts better take off hence normal ECM mode.
